My IPhone is beeping like a smoke detector?

I have an IPhone 4 and it recently just started beeping randomly like a smoke detector. I restarted it, and still it happened again. What is this and how do I fix it?

Hmm

Mine started doing that. I don't have a definite answer but someone else said to clear your safari history. I'm not sure what a permanent fix is for it.

  • White smoke came out of my iphone battery? So I have a iphone 4s and I accidently poked a hole in the battery and white smoke came out I was wondering will it be safe to charge or turn it on because I need a phone. NO INSULTING answer. If you r going to say something stupid then don't even bother writing anything. PS I'm not the one who did this
  • Smoke effect app? For pictures? Does anyone know an app for the iPhone that has a smoke effect in a way that would make me look like I'm smoking? I want to trick my friends and make it look real any one know?
  • Smoke coming from iPhone headphone jack? I dropped my phone in water and put it in rice. When I took it out everything was working except i had a piece of rice stuck in the jack. I tried to use a needle to get it out but i went too far and the jack started smoking and my phone won't turn on at all now. Is there anything I can do? Can i get it fixed or will it have to be replaced?
  • Smoke came out of iPhone 4S and will not turn on? It's really hot and I don't know what to do and I do not have the time or money to get a new phone.
